# KHOB, 325 text lines

325 Khmer text-line images with their transcriptions, cropped from the [Khmer OCR Benchmark (KHOB)](https://github.com/EKYCSolutions/khmer-ocr-benchmark-dataset) by EKYC Solutions: scanned Cambodian government documents with clean backgrounds and compression artefacts. One image is one line.

This is the KHOB test set in the [Netra OCR](https://github.com/netra-ai-lab/Netra-OCR) results, where the recognizer scores 0.96% CER with beam search and 1.29% greedy.

| Column | |
| --- | --- |
| `image` | the line crop |
| `label` | its text |
| `file_name` | the original crop's name: task, document and line number |

## Use

```python
from datasets import load_dataset
ds = load_dataset("Netra-Lab/khob-eval", split="train")
```

With the Netra OCR repository, the `khob` preset scores any model on it:

```bash
bash training/evaluate.sh published --test khob
```
